Dear, Mr
I didn't find the maximum input current of the TPS65287 in the data sheet.
Please, advise.
I'm going to use the TPS65287 in mode:
- Vin =+12V;
- Vout1=+3.3V (about 3A);
- Vout2=+5V (about 2A);
- Vout3=+10 (about 1.5A).
Is it right?
Best regards. Vladimir
Hi, Vladimir
I afraid TPS65287 cannot support your application.
The big concern is IC's temperature.
Below is package dissipation, at 25C, IC only can bear 3.33W.
For 3.3Vout1, assume the Eff is about 90%, then the Pd=1.1W.
For 5Vout2, assume the Eff is about 85%, then the Pd=1.76W.
For 10Vout3, assume the Eff is 75%, then the Pd=5W.
The total Pd=7.86W, which will cause IC triggers over temperature protection.
